Configuring NAT failover
Configure NAT failover to allow a primary interface (for example, T1 WAN
bundle) using PAT to failover to a backup interface (for example, PPPoE or
ISDN). In this case, when the primary interface is up, packets going out
through the interface are translated using the IP address of the primary
interface. When the primary interface goes down, the IP address of
the backup interface is used for the translations, and the stale firewall
connections are flushed.
